it is tempting to compare a repeater to an amplifier, but the comparision is inaccurate. according to Forouzan, an amplifier cannot discriminate between the intended signal and noise; it amplifies equally everything fed into it. a repeater does not amplify the signal; it regenerates the signal. when it receives a weakened or corrupted signal, it creates a copy, bit for bit, at the original strength.
a repeater is a regenerator; not an amplifier
a repeater forwards every bit; it has no filtering capability
a repeater connects segments of a LAN

∙ 12y agoAn 'amplifier' usually refers to an audio amplifier for a HiFi stereo system.
(Although amplifiers are used in other devices, such as Radio transmitters, and is an electronic device for making a signal bigger.)
A stereo amplifier usually has inputs for various signal sources, such as phono, microphone, tuner, aux etc. It has outputs for speakers. It takes a small input signal and boosts it to drive a loudspeaker and has controls to select the input and alter the volume and tone.
A receiver, generally refers to a dedicated radio receiver. It may have a choice of wavebands and a display to show what it is receiving.
A receiver is a complete unit which has it's own loudspeakers or can drive external loudspeakers.
A 'Tuner', on the other hand, is a radio receiver without it's own audio amplifier.
The 'Tuner' is used as an input source for the amplifier. The amplifier may have a Tuner input, or you can use the 'Aux' input.

What is the difference between an amplifier and an amplified chord?
An amp is what produces the sound, however the amp cord is what carries the sound. Some instruments do not need an amp cord. Stated in another way, an amp (or amplifier) is the device that converts the electrical impulses from an instrument into amplified sound. The electrical impulses from the instrument are carried to the amplifier by an amp cord, or an audio cable. This is usually a shielded, two or three conductor cable with male plugs at either end.
What is the purpose of an AF power amplifier in a FM broadcast receiver?
After FM demodulation to the original AF signal it is necessary to amplify the weak AF signal to have enough power to drive speakers. That is the purpose.
Do you connect speakers to receiver or amplifier?
Depends on what your definition of "receiver" is, but most of the time - to the amplifier. Consider: if the receiver is some form of a device that receives some signal, and then decodes it to audio, then the receiver will hook into the amplifier, which in turn will drive the speakers (so the speakers go to the amplifier) if, on the other hand, the receiver is a part of a wireless connection between the amplifier and speaker, then it really serves the role of a cable, so in essence you're again connecting the speakers to an amplifier (only using the receiver as an intermediary) You would have to specify your case.
What are the steps when a radio message passes through between the sender and receiver?

What's the difference between a powered and unpowered subwoofer?
Unpowered subwoofers take power from the receiver itself whereas a powered subwoofer has its own amplifier. This helps takesome strain off the receiver so powered subwoofers are considered a better option.

How do you wire your amp to receiver?
ideally "line out" on the receiver to "audio in" on the amplifier, left and right... If there isn't a "line out" use the the "audio out" but keep the volume on the receiver relatively low to prevent overdriving the inputs on the amplifier.
